Al, I appreciate the advice on A/C. Trying hard to get that fixed. hopefully have located a dryer that will fit the 3/8 flare fittings and will have that tomorrow. If anybody needs that part number for our Land Yachts for the filter dryer from O Reillys it is 33318. I have run out of time getting ready for trip so will have local garage do an evacuation and recharge. Hope that does the trick but will not know until then. Don I hope you can figure out your LP Heat. I assume you mean the furnace. I haven't had to work on mine yet but if I can help by making voltage checks or something let me know. I need to get some LP tomorrow and check everything out but I believe my furnace is still ok. My 1996 Atwood water heater does not like to restart sometime but if water gets cold enough (too cold) then it fires right up. Sounds like a sticking thermostat but I can live with that for my trip. Don I have tried to call a couple of times but can't catch you at home. UPDATE: Dumb me, All that was wrong with my water heater iwas that the flame/air adjustment was wrong. Read instructions on adjusting flame by loosening screw and setting shutter until yellow disiappears and now it starts fine every time with out the explosion! When all else fails........

To a new person like me as I read through the posts which include my own, it is a bit confusing on tire pressure. The magic starting number for most of is 70lbs and it is posted right on the driver side frame of the door. We are sometimes mislead because the tire may clearly say 110lbs and the tire installation guy is trained to set the pressure like it was a truck utilizing the max capacity of the tire. Unfortunetly that max setting is totally unsatisfactory for us and can produce an unconfortable if not a dangerous ride in our RVs. I learned the above the hard way. Another subject: I have also been told our front P30 air bags should be set to 50lbs. My question is: Is this a correct amount? I cannot find it in my manual though I admit the P30 Chevrolet part is missing from my AS book. I just removed and replaced my original Magnam A/S shocks (almost 11 years old). The removed and imprinted Yellow A/S magnum shocks looked very similar to my new Yellow Monroe Magnum RV shocks that are now installed on my MH. And yes the old ones were pretty far gone. I am trying to get my AS performance up to spec and seem to be learning something new every day.

Yes 50 to 55 Lbs is the proper inflation level for the front bags. I do not know if this is actually documented anywhere. I have all my manuals and none of them have the proper air pressure listed for the front bags. Having them properly inflated makes a tremendous difference in the front end bounce. The coach will feel much firmer.

I think the pressure is set at the factory at 70 psi on the front air bags ( for my 1994), but I'll go check my A/S manual. Went and checked the manual and it states that Airstream sets the pressure to 70 psi prior to aligning the front end.

The following is directly from the Chevy owners manual for my 1994 Land Yacht:

For motorhome models, inflation pressure must be maintained between 10 psi min and 50 psi max on 4300 lb front suspensions, 40 psi min and 50 psi max on 5,000 lb front suspensions, and 60 psi min and 100 psi max on 5,500 lb front suspensions.

Before loading the vehicle, inflate the air cylinders to the maximum pressure. After loading the vehicle, decrease the pressure as needed to level the vehicle.

Note: the book also says the air cylinders are there to adjust vehicle trim and should be checked monthly.

A big thanks

I wanted to thank everyone on this thread for some great information. I spent a lot of time getting my suspension back to stock (or better than stock) but still had a very harsh ride on bumps. I also had a little wandering in a crosswind or when getting passed by trucks.

It was driving me crazy. While the ride got progressively better with each repair/upgrade (shocks, steering stabilizer, rear air system straightened out) I began to notice that while smooth level highways gave a nice quiet ride...each overpass or small pothole rattled everything to the point that it sounded like the kitchen was going to fall out.

On my last trip I remembered this thread and lowered the tire pressure down from the max tire rating to the level set in the manual at a rest stop. What a difference! Rides like an Airstream now and is quiet, and smooth! - Thanks!

PS - I blew up a front bag overinflating it at a Flying J. I still need to replace it but I'm just too tired from the exhaust upgrades to handle getting "under the bus" again for at least a week!

Lightbulb airbag/tire pressure

My manual for p-30 chassis 1983, which my 1984 has, is listed as 55 pounds for the front airbags....this maual is also for shorter units.. but not for longer ones....

75 for front single tires, 60 for rear duals or 70 for a full last post on this thread indicated how badly my unit handled with the 100 pounds tire dealer put in the 110 rated tires......

using the links listed above that would be over the 95 pound rim strength rating Airstream lists and even if the rims held, I would have had over 22,000 pounds capability which is about 20/25 percent more than the chassis can carry by design strength....

Result bad ride...poor handling...longer stopping distances...and probable overloading failures....pressure is very important in these rv's...jem
